Patent GB-2201550-A (GB)
Title: Antenna with signalling device
Inventor: ANGELOU BARBARA CHRISTINE
IPC: H01Q1/06
Filed: 1987-02-05
Abstract: An antenna arrangement comprises a signalling device, eg a lamp 18, mounted on the antenna and means for superposing a powering current for the signalling device onto a radio frequency signal to be transmitted by the antenna. The arrangement further comprises means, eg. a capacitor 20, for filtering the signal to be transmitted and the powering current so that a substantial portion of the signal to be transmitted does not pass through the signalling device. The superposed signal to be transmitted and powering current are fed from a transmitter 30 via an impedance network 34. The antenna may be a folded monopole 10, 12. <IMAGE>

Title: Temperature control circuit
Inventor: FITZPATRICK JAMES
IPC: G05D23/22
Filed: 1987-06-16
Abstract: A control circuit for an electrical resistance storage system includes a solid state switch such as a triac (32) which controls the power supply to a heating element (30). The triac (32) is controlled by a driver circuit (34) in response to the output of a pulse generator (36) and a zero-crossing detector (38). The circuit (34) is controlled by an inhibit circuit (54) and an I.C. (46) including a comparator (50) adapted to compare the output signal from a thermocouple (44) with a preset reference and to control the driver circuit (34) and thus the triac (32) on the basis of the comparison. The thermocouple (44) senses the temperature of a refractory mass heated by the element (3). The power supply (40) for the circuits (34 and 46) is preferably provided by the mains supply powering the heating element (30). <IMAGE>

Patent GB-2215823-A (GB)
Title: Hot water boiler
Inventor: HATTRICK JAMES
IPC: F24H9/20
Filed: 1987-12-24
Abstract: A hot water boiler comprises a vessel or container 1 which has three compartments or chambers contained within the main body of that vessel or container. Water enters chamber 3 via a ball float valve 7 and fills the boiler to a predetermined level. Heat is applied in chamber 4 and boils the water which due to expansion is transferred to a draw off chamber 5, where upon it can be drawn off via a tap. The amount of water boiled is controlled by the action of a high level actuator 8 and a simmering device. The protection of the heating source is controlled by a low level actuator 9 which is identical to the high level actuator. <IMAGE>
Patent GB-2212784-A (GB)
Title: Metered beverage dispensing apparatus
Inventor: GLOVER BRIAN
IPC: B67D1/12
Filed: 1988-11-24
Abstract: In a metered beverage dispense system a pressure sensing switch (8) is located in the line (5) closely adjacent the outlet of the meter (4) and this switch is arranged so that it detects the point at which a rapid and significant fall in pressure occurs adjacent the meter outlet. This pressure drop results from the metering ball seating firmly to close the outlet of the meter and provides a positive and reliable signal of the end of the dispense stroke. As soon as the pressure drop occurs the switch operates to cut the electrical supply (7) to the tap (6) thereby instantly shutting off the outlet and maintaining pressure within the line (5). <IMAGE>
Patent GB-886391-A (GB)
Abstract: 886,391. Pivots. SMITH & SONS (ENGLAND) Ltd., S. Oct. 27, 1960 [Nov. 4, 1959], No. 37409/59. Class 65(2). [Also in Group XX] In a rate of turn gyroscope the fluid tight gimbal 4, enclosing the rotor 2, is pivoted about an axis 11 within a casing 9, containing silicone or other fluid, by means of supports 10, each of which includes a thin torsion bar 12 and a cylindrical part 13 which is surrounded by a low friction bearing 14, such as a cylindrical ball bearing or a journal bearing lined with polytetrafluoroethylene or other low friction material, the bearing 14 being normally spaced from part 13, by, e.g. 0.0005 to 0.003 inches.

Patent GB-2236604-A (GB)
Title: Protecting against the unauthorised use of software in a computer network
Inventor: CORBIN JOHN RICHARD
IPC: G06F21/62
Filed: 1990-04-30
Abstract: The present invention provides to a software application the verification and licence check out functions which are normally performed by a licence server. The encrypted licence information is contained in a licence token, and is stored in a database 17 controlled by the licence server 15. In contrast to the prior art where the server either grants or denies the request after verifying the user's credentials, the server in the preferred embodiment of the present invention finds the correct licence token for the software application and transmits the token to a licencing library. A licence access module attached to the application decodes the token. Routines in the licencing library coupled to the software application verify the licence information before issuing the licence and updating the token. The access module then encodes the updated token before returning it to the server. Because the verification and issuing function of a token are performed by a software application, the application rather than the server becomes the point of attack by unauthorised users. Reverse engineering the access module is less rewarding than attacking the server because the module reveals the contents of a small fraction of a database of licences. <IMAGE>
Patent GB-2236079-A (GB)
Title: Foldable trolley structure
Inventor: HILL NIGEL
IPC: B62B3/02
Filed: 1990-05-10
Abstract: A foldable structure preferably a shopping trolley comprises at least three resilient scissor elements disposed in a regular array, each element being pivoted to at least one adjacent element whereby elements may be moved from a folded to an unfolded condition. Toggle means (4) are associated with one or more of the scissor elements and are moveable from an at rest position in the folded condition of the structure to a locked position in the unfolded condition thereby to retain the scissor elements in their unfolded condition. A flexible retainer means (5), eg a flexible web or an adjustable bracing wire, conjoining one end of each of the scissor elements to an adjacent end of another element stresses the resilient scissor elements in the unfolded condition against the force exerted by the toggle means in its locked position. The scissor elements are extended rearwardly to form handles (7) and are preferably of aluminium. <IMAGE>

Patent GB-2254649-A (GB)
Title: Window hinge.
Inventor: MOORE JOHN
IPC: E05D15/30
Filed: 1991-04-08
Abstract: A window hinge comprises a flanged track (1) arranged to be fixed to a window frame at points (2, 3, 4 and 5) and a ventarm (6) arranged to be fixed to the window frame at points (7, 8 and 9) and having a point (24) at its top which enters a recess (25) in a cap (26) of plastics material when the window is closed. A metal spacer is fixed beneath the top of the ventarm (6) and has the same configuration but slightly smaller than the top so that when the point (24) engages the recess (25) there is a small clearance between the spacer and the recess. Thus when wear of the ventarm takes place the spacer makes contact with the recess preventing increase in wear. <IMAGE>
